Araiguma respin beta 1

NOTE: The main executable links the still in beta (after more than a year) Mono.Cecil 0.10 version. The binary injected into the instrumented code does not. Rather than hold my releases on the Mono.Cecil schedule, I make this disclaimer instead.

1.6-beta (Araiguma respin preview)

• The AltCover.Runner helper program in 1.5 used named pipes, collecting data from the instrumented process as it ran; this was strongly platform dependent and brittle -- and was not compatible in the classic framework with the .net 2 support.
• Named pipes eliminated in favour of writing to a file and post-processing
• Mechanism compatible with .net 2.0 so made available everywhere
• separate .net core only runner program eliminated in favour of an alternate command-line interface for the main AltCover
